7 Claims.

This invention `relates to improvements in corner structures for boxes and the like. While the invention is capable of use on the bottom corners and the bottom of any box, it is particularly adapted for boxes which are subjectedduring use to considerable wear at the bottom corners and the bottom, one example of such boxes being bread boxes which are commonly used to transport bread to stores and to the household consumer.

The principal object of the invention is to provide a novel combination corner piece and shoe clamp for boxes of this character which will withstand wear, permit easy replacement of the shoe members when worn, and permit ready stacking of the boxes in nested fashion.

Another object of the invention is to provide a novel device of this character which is simple in structure and which may be manufactured economically.

V.'Ihe invention may be more clearly understood by reference to the accompanying drawing illustrating a preferred embodiment.

In the drawing:

Fig. 1 is a perspective view of an inverted box with the devices of the invention applied thereto;

Fig. 2 is a fragmentary sectional detail view taken along line 2-2 of Fig. 1;

Fig. 3 is a perspective view of one of the corner pieces;

Fig. 4 is a fragmentary perspective View of an end portion of one of the shoe members; and

Fig. 5 is a perspective view of one of the shoe clamps.

In the box l shown in Fig. 1, there is applied to each of the bottom corners of the box a device 2 constructed in accordance with the invention, as hereinafter described, and, in addition to reinforcing the corners of the box, these devices serve to secure shoe members 3 which extend longitudinally along the bottom of the box near the opposite edges. As well known, these shoe members and the corner devices take the wear to which the bottom of the box is subjected. The box l may be formed of any suitable material. Preferably, however, this box will be formed of some relatively durable material such as vulcanized bre or phenolic resin-impregnated fibrous material. Such boxes have been used in the past and have been found to be satisfactory.

In accordance with the present invention, there is provided a corner piece ll, as shown more clearly in Fig. 3. This corner piece is preferably formed of sheet metal and comprises side flanges 5 and a bottom 6. The side iianges and bottom are provided with apertures l for the reception oi rivets la or other fastening devices by which the corner piece is secured to a bottom corner of the box, as illustrated in Fig. l, the side flanges 5 being secured to adjacent sides of the box. The bottom il is out away to provide a recess 8 and the edges about the recess are flanged, as shown at 9, so as to seat the end of a shoe member 3.

As shown in Fig. 4, the end portion `of the shoe member 3 is recessed at i0 to receive the flanged edges 9 when the shoe member is seated within the recess 8, as shown in Fig. 2. The end portion of the shoe member is also recessed at H to seat the shoe clamp l2 (Fig. 5) which has side ilanges I3 and an end flange l@ adapted to t over the end of the shoe member and over the anged edges 9, as shown in Fig. 2. The shoe member is provided with apertures I5 and the shoe clamp has corresponding apertures I6 in order that these parts may be secured to the bottom of the box by means of rivets Il or the like, as shown in Fig. 2. The shoe member is preferably formed of hard wood, while the shoe clamp is formed of sheet metal.

It will be apparent that the device provided by the invention serves as a rigid reinforcing device for the bottom corners of the box and also holds the shoe members securely in place. Moreover, the shoe members may be readily replaced when wom, it being merely necessary to remove the rivets Il to remove the shoe clamp I2 and the shoe member 3 without disturbing the corner piece 5. This is a very important advantage. It will also be apparent that the device of the invention enables stacking of the boxes as is the common practice.

Although a single preferred embodiment of the invention has been illustrated and described, it will be apparent that various modications are possible within the scope of the invention.

I claim:

1. A combination corner piece and shoe clamp for boxes and the like, comprising a corner piece adapted to be secured permanently to a corner of the box and to have a shoe member associated therewith, a shoe clamp adapted to t over an end of said shoe member and serving with said corner piece to hold the shoe member in place, means on said corner piece for fixing said clamp in position, and means for securing said clamp to the box.

2. A combination corner piece and shoe clamp member, a channel-shaped shoe clamp adapted to fit over an end of said shoe member and serving with said corner piece to hold the shoe member in n place, means on said corner piece for iixing said clamp in position, and means for securing said clamp to the box. f

3. A combination corner piece and shoe clamp e for boxes and the like, comprising a corner piece y adapted to be secured to a corner of a box andl having side flanges and a bottom provided with iianged edges defining a recess for the'reception of a shoe member, a shoe clamp having flanges or sides adapted to t over said flanged edges to hold said shoe member in place, and means for securing said clamp and said member together and to the bottom of the box.

4. A combination corner piece and shoe clamp for boxes and the like, comprising a corner piece adapted to be secured to a corner of a box and having side flanges and a bottom provided with flanged edges dening a recess for the reception of a shoey member, a shoe clamp having flanges or sides adapted to fit over said flanged edges to hold said shoe member in place, and fastening means extending through said clamp, said member and the bottom of the box to secure the said elements together.y

5. A corner piece, shoe clamp 'and shoe assembly for boxes and the like, comprising a corner piece adapted to be secured to a corner of a box and having side flanges and a bottom provided with flanged edges defining a recess, a shoe member adapted to seat in said recess and itself being recessed to seat said flanged edges, a shoe clamp having flanges or sides adapted to t over said anged edges, said shoe member being recessed to seat said shoe clamp, and means for securing said clamp and said member together and to the bottom oi the box.'

6. A combination corner piece and shoe clamp for boxes and the like, comprising a corner piece adapted to be secured vto a corner of a box'and having side anges and a ybottom provided with a Walled recess for the reception of a shoe member, a shoe ciamp having anges or sides adapted to it over said shoe member with said iianges adjacent the Walls about said recess, whereby said 'clampl is vprevented from moving laterally, and means for securing said clamp to the bottom of the box. l

'7. A combination corner piece and shoe clamp for boxes and the like, comprising aV corner piece adapted to be secured to a corner of a box and having side anges and a bottom provided'with a Walied recess for the reception oi a shoe member, a channel-shaped shoe clamp having flanges or sides adapted to t over said shoe member with said anges adjacent the Walls about said recess, whereby said clamp is prevented from moving laterally, and means for securing said clamp to the bottom of the box.
